ARBOR PRESS.

Application filed'Nov ember 26, 1923. Serial No. 677,011.

Our invention relates to improvements in arbor presses, one object thereof being to provide a device of this nature adapted not only for arbor press work under various conditions, but for shearing and for punching, whereby the numerous needs in suchclasses of work may be expeditiously met with equipment ,low in cost and necessitating limited operating space.

Another object is to supply a device of the present nature having parts readily interchangeable and adjustable,whereby selected companion elements may be quickly and easily brought into co-operation.

lVith the foregoing and other objects in view, which will appear in the following description, the invention resides in the novel combination and arrangement of parts and in the details of construction hereinafter described and claimed.

In the drawings, Fig. 1 is a perspective view of a device embodying our invention; Fig. 2 includes perspective views in detail showing additional tool members supplied for the pressure bar; Fig. 3 is a perspective view illustrating a composite female die, which is interchangeable with the similar die shown in Fig. 1; Fig. 4 includes perspective views of different male die members, for application to the chuck (left view, Fig. 2;)?Fig. 5 is a plan view of the tool receiving table on the bed of the press; Figs. 6 and 7 are sectional views taken, respectively, on the lines 66 and 7-7 of Fig. 5 and Fig. 8 illustrates a number of different object holding members severally applicable to the seat support on the table.

Referring to the drawings, it will be observed that the press proper is constructed along conventional lines, the same embodying a bed 10, with a standard 11 thereon turning forwardly, at its upper end, over the forward end of the bed 10. Slidable vertically in the standard 11 is the usual rackbar 12, at times hereinafter called a pressure bar. A stub-shaft 13 journaled in the standard 11 is fitted with a spur gear (not shown) meshing With teeth (not shown) on the rack bar, 12 in accordance with usual practice.

A handle 14 slidably adjustable in the end of the stub-shaft 13, as 1s common, provides for elevating and depressing the. pressure bar 12. The press base as at 15, the forward end of the bed 10 preferably overreaching the support so as to leave the notch 10* in saidbed entirely unobstructed.

Severally applicable to the reduced rounded end 12 (Fig. 2) of the pressurebar 12 are tool members a, 6, 0 and (Z. A table 6 resting on the bed 10 of the press turns on a bolt 16 reaching through the centerof said table and threaded in said bed. This table 6 carries tool members 7, g, h and i for cooperation with the tool members a, Z), 0 and d.

The tool member dillustrated in Fig. 1 includes a yoke-like body 17 and a block 18 journaled 011 a pintle 19 between the depend ing-branches of said body. ,Male die memrests upon any suitable bers 20 extending radially from the block) l8 are selectively set in depending operative position by turning the block 18 and secnring the same with a sliding lock pin 21, which reaches through said body and into apertures formed in the block 18 to, accord f with the operative positions of the different die members 20. Thedisc-like tool member 7 (F ig. 1) is the companion of said tool member a. Said member 7 is removably and revolubly seated in a depression 22 in the table 6, a bolt 23 reaching through said member f and threaded in the table 6 serv ing as an axis on which said member may be turned. This female tool member f has a bore 21 for each male die member 20 of the tool member a and said bores are brought into alignment with their respective dies 20, operatively positioned, by appropriately turning the tool member f. A locking pin 25 sliding in an aperture 26 in the table fits in apertures 27 in the tool member 7 and se cures said member in selected operative p0sitions. A second female tool member 9 (Fig. 3), similar to the tool member f (Fig. 1) is interchangeable with said member 7'. Companion to said second member 9 are male dies 28 4:), which are interchangeably applied to the tool member d (Fig. 2) consisting of a chuck for removable attachment to the pressure bar 12. Said member 9 turns on the bolt 23 in the de pression 22 in the table c, and is secured I removable. applicable to-the pressure bar 12,
